Are things getting stale with your AR-15? We all know that variety is the key to stimulation, so what can you do to spice things up?

Explore a new shooting niche with this sturdy cartridge. 

Why should you choose the 300 BLK for your AR-15?

  • Lower powder charge saves barrel life
  • Appropriate for many state hunting regulations
  • Ideal for using with a suppressor
  • Subsonic without a suppressor

As you can see, it’s a specialty cartridge that shines at short-range shots or in a suppressed AR-15.

A Quick Guide to Distance: How Far Will Your Bullet Go?

For an AR-15 chambered in 300 BLK keep these rough measurements in mind:

  • Long Range: 300 yards and above
  • Medium Range: 150 – 300 yards
  • Close Range: Up to 150 yards

Although it’s not the most powerful cartridge, it still remains the most quiet and effective at close range. Then again, who says it’s not capable of going farther? Our favorite thing about this cartridge is how versatile it can be.

So what about you?

Are you ready to step up to longer distances or just improve your short shot? A scope will be beneficial for both.

What Magnification Do You Need?

Although it’s growing in popularity, working with this cartidge can mean a slight learning curve. That’s where a 300 blackout scope comes in to save the day!

However, there isn’t one scope to fit every person. Your typical trip in the field will determine what kind of scope you need.

  • Long Range (300 yards and above)
  • At this range, you likely won’t be taking down much game due to the modest penetration of this caliber. However, you can still show off at the range and leave your crew speechless. If this sounds like you, you’ll want at least 9x magnification or higher.

  • Medium Range (150 – 300 yards)
  • At this range, the coyotes and foxes will be wishing they’d found other property to trespass. If you want to clear your land of varmints, you’ll use about 5 – 9x magnifications.
  • Close Range (Up to 150 yards)
  • Here, you can definitely hunt small game or hit a bullseye dead-on. Since this is the range where this caliber naturally excels, using 1 – 4x magnifications gives you a huge boost.

Let’s see what kind of scopes give you an advantage over the competition!

Folks with a 300 Blackout-chambered rifle might want to check out this compact and tactical scope from Trijicon. The TA02 ACOG is a fixed magnification scope rather than a variable magnification model, meaning it is set at a single zoom setting. In this case, it’s 4x with a 32 mm objective lens.

But this is great if you want a tactical optic suitable for hitting relatively close to midrange targets or for combining with red dot or other sights on the same platform. The optic is fully night-vision compatible as well, cementing this is a great tactical choice for serious 300 Blackout enthusiasts.

We also like that this comes with lens caps by default. You’ll be able to protect your lenses, which are already multicoated, from further wear and tear or debris scratching thanks to its inclusion.

LED Reticle

The big selling factor with this optic is the illuminated reticle. It’s a BDC or bullet drop compensating variety, meaning it features additional hashmarks on the bottom vertex to help you hit more distant shots. It’s a great choice for those who like to push out the effective range of their 300 Blackout rifles.

The reticle itself is fully illuminated, featuring an array of brightness settings that you can switch between using a control on the side of the optic. The illuminated reticle runs on a basic battery that should last for several thousand hours before needing to be replaced.

The Bottom Line

All in all, the TA02 ACOG is a great secondary optic if you already have a closer range scope for your 300 Blackout. Consider pairing it with another optic to cover all of your major ranges or use it as a primary tactical scope for engagements out to about 200 yards or so.

UTG has a fantastic catch for anyone who never knows what to expect in the field. If you need short range one minute and quickly scale up to long range, you can do that ¼ MOA at a time.

No matter how far you’re aiming, you’ll never have to worry about parallax. From 10 yards to infinity, your crosshairs will always hold steady. However, using the side wheel adjustable turret (SWAT) that accomplishes this is a small inconvenience since it’s a little tight.

Otherwise, the only other complaint is the hefty 2 pounds this scope adds to your rifle. Some prefer it, others don’t, but either way it takes some practice to adjust.

Now that we have the bad news out of the way, let’s talk about the highlights!

Zero locking turrets save you time and frustration in the field. That means once you zero in, you’re set. Simply zero in and lock it, then on your next shot all it takes is a tap and you’re back in action!

Believe it or not, the target turrets aren’t the only feature that locks and resets in a flash.

Illumination Enhancing (IE) Reticle

Although IE reticles aren’t for everyone, they’re often the light of many rifle owners’ eyes – literally.

Even better? With this scope, you get 36 different color options to complement the high-quality emerald lens. Switch through them effortlessly with the tap of a button. Then when you find one you like, lock it in and snap back to it in an instant!

The IE feature does make this scope slightly heavier, but it’s well worth the “enlightening” experience!

The Bottom Line

If you want big benefits from a small package, look to UTG. Even though it’s under a foot long, this scope lets you cover a broad distance in any light setting. Best of all, it doesn’t waste any time since its best features lock and reset in a snap. Will it be your rifle’s next companion?

Vortex Optics, one of the best scope manufacturers in the industry, also has a great choice for 300 Blackout users. The Strike Eagle is a second focal plane scope that can magnify between 1-6x and that features a 24 mm objective lens. Therefore, it’s a great choice for both close and mid-range engagements, and its small size allows you to combine it with other optics depending on the design of your rifle and rails.

Regardless, this scope features an updated magnification ring that includes a throw lever for fast and easy adjustments between the different magnification settings. It also comes with a fast focus dial on the eyepiece, plus anti-reflective coatings on all glass surfaces to minimize the likelihood of the sun glaring in your eye right before a shot.

The scope overall is quite durable as well. It is O-ring sealed and nitrogen purged to ensure water and fogproof performance under any circumstances. It’s made primarily of aircraft-grade aluminum, which means it only weighs about 18 ounces despite being extremely recoil resistant.

Illuminated BDC Reticle

Of special note is the illuminated BDC or bullet drop compensating reticle. This reticle is perfect when trying to hit shots at 6x magnification or otherwise having to estimate your round’s drop over a significant distance.

The reticle is illuminated to boost your accuracy even in bright daylight conditions. Fortunately, you can change the intensity of this brightness setting by using a special dial opposite the elevation dial on the scope’s body.

The included windage dial also allows you to compensate for this factor when needed.

The Bottom Line

In the end, the Strike Eagle is an affordable and super functional scope that’s perfect for both close and mid-range engagements. The illuminated reticle adds additional value and the optic’s overall ease-of-use will surely make it a favorite for many 300 Blackout owners in the future. Would also be a nice M4 optic.

4. Primary Arms 1-6x24mm SFP Gen III Illuminated Riflescope

Check Price on OpticsPlanet

Primary Arms offers a scope similar to the above Vortex Optics model, ranging in magnification factors from 1-6x and featuring a 24 mm objective lens. It also has a second focal plane reticle, so it won’t change sizes as you swap between magnification settings.

But it has other features that might make it worth your while, such as a fast focus eyepiece that can help you scope in to your target and track a fast-moving varmint or another critter quickly. It’s a great hunting eyepiece, to be certain.

But it’s also a great general-use or target shooting scope thanks to its capped and finger adjustable windage and elevation turrets. The turrets are relatively low-profile so you don’t accidentally bump them with your fingers when moving your position or making other adjustments.

The scope, like many other top models on the market, is made primarily of 6063 aircraft-grade aluminum and is designed for waterproof and fogproof functionality. Therefore, it’s a good tactical or hunting scope depending on your needs.

Red Partially Illuminated Reticle

This scope’s optic is also illuminated, though it is red by default. The illuminated optic includes bullet drop compensation hashmarks, as well as additional holdover points for wind compensation and moving target leading. It even includes special holdover points for range estimation. It’s a true marksman’s reticle through and through.

You can adjust the illumination settings using a side-mounted control. To round out the scope’s value, it comes with a pair of flip-open lens caps for both ends, allowing you to protect the already high-quality glass from regular degradation due to dirt or too much light exposure.

The Bottom Line

Primary Arms’ SFP Gen II Riflescope is a great choice if you want something reasonably affordable and certain to last for at least a couple of years of regular use. It may also be a better choice than other options if you enjoy highly detailed and holdover-point-rich reticles that can provide a ton of information to help you hit more distant shots.
